Consider the case when pmspr = 0x00feffffffffffff;

We are interested in extracting the value 'fe'. And ensure that when
we store this value into an int, we get the sign extension right.

So the following doesn't work:

   pstate_id = (pmspr_val >> 48) & 0xFFFFFFFF;

What about pstate_id = (pmspr_val >> 48) & 0xFF; ??
